Hi jeanmarc,
I succesfully installed 123 solar with SBFspot (you can reach it at http://caluso.ns0.it/123solar).
I only have some problem:
- in the info page, in the inverter info section I only see a "Unable to open 'date_time_zonespec.csv'". Why? (I had to hard code the path of the program in SMAspot.php)
- I receive a lot of email every day with subject "123Solar: Inverter #1 Alarms Warnings digest" and body (for example):
"16/03/2015 18:36:00 ---
---16/03/2015 18:31:00 ---" (a line every 5 minutes).
Why? How can avoid this behaviour?

Moreover:
- I installed the system on a Pi2. During the day the CPU usage swings continuously from 1% to 25%. Is it normal?
- can I avoid the 0 Vac values in the graph? The SMA provides 0 Vac before starting production and after stopping production.
